Publication date: 2026-05-21

Last updated on: 2026-05-22

Assigner: Trend Micro, Inc.

Description

An origin validation vulnerability in the Apex One/SEP agent could allow a local attacker to escalate privileges on affected installations. This is similar to CVE-2026-45206 but exists in a different process protection communication mechanism. Please note: an attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.

Attack-Flow Graph

Executive Summary

This vulnerability is an origin validation flaw in the Apex One/SEP agent. It allows a local attacker, who already has the ability to run low-privileged code on the system, to escalate their privileges. The issue is related to the process protection communication mechanism and is similar to another vulnerability identified as CVE-2026-45206.

Impact Analysis

If exploited, this vulnerability can allow an attacker with limited access to gain higher privileges on the affected system. This means the attacker could potentially perform actions that require elevated permissions, compromising the security and integrity of the system.

Mitigation Strategies

To mitigate this vulnerability, ensure that you update your Apex One/SEP agent to the latest version provided by Trend Micro that addresses this issue.

Since exploitation requires prior ability to execute low-privileged code, restricting such access and monitoring for suspicious local activity can help reduce risk.
